> From Adam w.r.t. HFile splitting:
> There's actually a good number of messages of that type (HFile no longer fits 
> inside a single region), unfortunately I didn't take a timestamp on just when 
> I was running with the patched jars vs the regular ones, however from the 
> logs I can say that this is occurring fairly regularly on this system.  The 
> cluster I tested this on is our backup cluster, the mapreduce jobs on our 
> production cluster output HFiles which are copied to the backup and then 
> loaded into HBase on both.  Since the regions may be somewhat different on 
> the backup cluster I would expect it to have to split somewhat regularly.
> This JIRA complements HBASE-3721 by parallelizing HFile splitting which is 
> done in the main thread.
